[CMake] Adding entries to the info.plist file for OS X .app bundles.

[Michael Jackson]

Is there anything in the latest CMake version to add additional entries into the plist file for .app packages? I specifically need the following:

<key>NSPrincipalClass</key>
<string>NSApplication</string>
<key>NSHighResolutionCapable</key>
<string>True</string>

to support Retina displays for our app. Should I just create my own template .plist file and use "configure_file" to add items into the file?

Thanks
